Insights into the Nature of Quantum Emitters in Electron-Irradiated hexagonal Boron Nitride
Mouli Hazra, Anna Rupp, Mohammad N. Mishuk +9
Quantum emitters in hexagonal boron nitride (hBN) have emerged as a promising solid-state platform for quantum technology applications. However, a persistent challenge in the field…
Sensitive biodetection in flow using metasurface hosting quasi-bound state in the continuum resonances
Sarah L. Walden, Anna Fedotova, Dmitry Pidgayko +4
We have designed optical metasurfaces hosting high-quality factor quasi-bound state in the continuum (q-BIC) resonances for optical biosensing in flow. The unit cell of the metasur…
Design strategies for efficient, fabrication-feasible extreme-ultraviolet metalens
Shiu Hei Lam, U Abinash Patro, Jan Rothhardt +1
The concept of metasurfaces was recently applied to the extreme ultraviolet (EUV) spectral regime, providing a new opportunity for transmissive focusing elements in a regime where…
Directional and contra-directional coupling in Huygens' metawaveguide microring resonators
M. Saad Bin-Alam, Yunus Denizhan Sirmaci, Alejandro Fernández-Hinestrosa +8
Huygens' metawaveguides represent a transformative concept in photonic device engineering, enabling unprecedented control over light propagation. This study presents, for the first…
Towards Polarization Routing of Magnetic and Electric Dipolar Emission with Dielectric Metasurfaces
Marijn Rikers, Ayesheh Bashiri, Katsuya Tanaka +4
We investigate the polarization properties of emission associated with the magnetic dipole and electric dipole transitions of europium(III) coupled to an anisotropic dielectric met…
